- Primary Outcome Measures
Name Time Method <p>Main study parameters<br /><br>Cephalometric analysis will be carried out on the pre-operative,<br /><br>post-distraction and these radiographs. The following measurements will be<br /><br>made:<br /><br>* SNB-angle: sella/nasion-mandibular point B<br /><br>* SN-MP: sella/nasion- mandibular plane<br /><br>* Point B in respect to x and y-axis<br /><br>* x-axis= SN, y-axis: perpendicular line to x-axis<br /><br>Primary parameter is to establish horizontal mandibular relapse. This is<br /><br>defined as change of position of point B in a horizontal (mandibular) plane.</p><br>
